I .ronrmnmm Specification of Letters tan, Patented May 14, 1918.

which the following is a specification.

My invention is designed to aflord a simlple, cheap,- compact, andeffective portab cheating device adapted for use as an expedient fortemporarily acquiringwarmth for person'or situation according to cad--genciesg and it consists essentially of a heatmg device in which acatalytic agent may since the sha be exposed to contact with emanationsfrom a volatile oxidizable substance as well as to the atmosphere,substantially as herein after set forth and'claimed specifically.

In the accompanying drawings,

Figure 1, is a central vertical sectional elevation of a deviceadaptedto thejpracticai embodiment and use of my invention, with thecover in place, and communication closed between the catalytic cage andthe reservoir of volatile material;

' Fig. 2, is a top view of the device with the cover removed, andshowing communi cation between the catalytic cage and the volatilizationchamben partially closed; a

Fig. 3, is a partial top view, with the catalytic cage removed and theport to the volatilization chamber open to the fullest extent;

Fig. 4, is a side elevation of the. catalytic cage; and V Fig. 5, a viewof the under side thereof.

Fig. 6, is a plan of a portion of the top of the reservoir showing amodification in the means of supporting the catalytic agent;

Fig. '7 is acentralvertical sectional elevation oi the parts shown inFig. 6.

In the dra I have shown my portable heater as cylin 'cal in generalconfigura, tion, although this is not an essential feature or contour ofthe device may bevaried as ound desirable or expedient in adapting myinventiomto the practical requisites of various uses without departingfrom the'spirit and intent of said invention,-.the essential feature ofwhich is that of a catalytic agent interposed between the atmosphere anda chamber or reservoir containing a volatile substance the emanationsfrom which are subject to oxidation.

Thug-in the drawings herewith submitted num, or of several R, representsa reservoir containing volatile material V, either hquid, solid, or inany intermediateconditiomas for instance alcohol, liquid or solid,ether, turpentine, or any other desired or available volatile substanceoxidizable in the presence of air and in convolatile substance is liquidor semi-liquid, or of explosive character, and absorbent material may berovided in the reservoir to stabilize the 'fiuid contents, feed the sameto junction with a catalytic agent; When the the catalytic cell C, by caillary. attraction,

and counteract any ten ency to ignition within said reservo1r R. Forthis purpose cloth, cotton, infusorial earth and other suit able materials"may be provided in the res ervom- The cage or holder C, for thecatalytic material 0, may be of any desired form and constructionprovided it is furnished with retlculated screens 0', 0 or theequivalent thereof which, while confining the said catalytic material0", within the cell C catalytic cell C, isshown as in the form of aflanged cylindrical box, fitting into the' neck 1', of the opening inthe top of the.

reservoir R, and detachable therefrom: .to

admits air thereto on one side and olndizable vapor on i ;he other. Thusin the drawings the ployed for the purpose I prefer platinum on accountof its relatively high catalytic force or power,-and it may be usedeither in the form of platinum wire, platinum sponge, platinum black,platinum asbestos, platinum pumice or any OthfilifilEGPBl'fltlOll orplatierent' platinum preparations, as may be found most expedient.

In order to control the feed of om'dizable vapor to the catalytic cellC, I provide a valve or damper D, of any suitable kind,-a

simpleform being that shown by way of illustration in the drawings,inxwhich said damper D, consists of a pivotally supplorted platepositioned on the underside of t e top' sulpport or of the reservoir R,the pivotal trunnion d, to which the dam r p to D, is rigidly attached,extending a ve said top and being provided withvme'ans whereby It may beturned manually, as'by the lateral arms d, d:

Obviously, by prescribing the amount of oxidizable vapor admitted to thecatalytic" ce11C,thed

at; of

incandescence therein may be controlled and regulated to suitrequirements,-the supply of atmospheric oxygen being. constant, and thechemical reactions superinduced on the catalytic surfaces beingdependent on' the amount of oxidizable vapor supplied thereto. Hence'the heat generated may be prescribed within suitable limits, and adaptedto the purpose for which the portable heater is to be used. l v

A cap .A, is preferably provided, fitting over the upper part of thereservoir B, and

application in medical treatment, etc.,1n'

which latter case it may be shaped to conform to the portion of the bodyto which it is to be applied. On a larger scale my portable heater mayalso be adapted for use as a supplementary heater for apartments andin'closures in very-cold weather, or where ordinary means ofheatingfail. In fact the adaptability of the principleinvolved is obviouslyvery extensive, so that I do not wish .to limit myself to the identical'formand construction of parts shown.

As antmstance in the connection the catalytic agent a", may be suspendedwith like result in the neck or port 1', of the reservoir R, by -othermeans than the reticulated screens 0, 2 as, for instance, in the mannerindicated inFlgs. 6 and 7, by stirrups 0 which are the equivalent ofsaid screens 0',

0 since they admitthe air and vapor to contact with the catalytic agent0, consisti,aee,1ea

ing in this case, say, ofa suitable mass of spongy platinum.

VVhatl claim as In to secure by Letters atent is,

1, A portable heater'of the character designated, comprising a reservoiradapted to contain a volatile oxidizable substance, and in conjunctiontherewith a catalytic cell invention and desire adapted to containcatalytic "material and to i receive vapor from said reservoir and alsoto admit atmospheric oxygen to said catalytic material, together with adamper in- 'terposed between-said cell and the said substance, and aremovable cover inclosing the upper part-of said reservoir and saidcata-' lytic cell and formed to admit. air to the v latter, and meanswithin the cover for rotating said damper for the purpose described.

2. A portable heaterof the character designated, comprising a reservoiradapted to contain a volatile omdiz'able substance, and

in conjunction therewith a catalytic cell adapted to contain catalyticmaterial and to receive vapor fromsaid reservoirand also to admitatmospheric oxygen to sa1d catalytic material, together withmeansdisposed beneath said cell and between the same and p the upper endof the reservoir for regulating the admission of oxidizable vapor to asaid catalytic-cell, and together with a removable coverinclosing theupper part of said reservoir and said catalytic cell and formed to admitair to the latter and-means within thecover for actuatmg said regulatingmeans, for the purpose described.
